Simple Heatin System Size: Wasnington State
<br /> This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2015 Washinqton State Enerqv Code(WSEC)and ACCA
<br /> Manuals J and S.This calculator will calculate heatinq loads oniv.ACCA procedures for sizina coolinq svstems should be used to determine coolinp
<br /> loads.
<br /> The glazing(window)and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of
<br /> 0.30. The incorporated insulation requirements are the minimum prescriptive amounts specified by the 2015 WSEC.
<br /> Please fill out all of the green drop-downs and boxes that are applicable to your project.As you make selections in the drop-downs for each section,
<br /> some values will be calculated for you. If you do not see the selection you need in the drop-down options, please call the WSU Energy Extension
<br /> Program at(360)956-2042 for assistance.
